Jack \Jack\ (j[a^]k), n. [Pg. jaca, Malayalam, tsjaka.] (Bot.)
A large tree, the {Artocarpus integrifolia}, common in the
East Indies, closely allied to the breadfruit, from which it
differs in having its leaves entire. The fruit is of great
size, weighing from thirty to forty pounds, and through its
soft fibrous matter are scattered the seeds, which are
roasted and eaten. The wood is of a yellow color, fine grain,
and rather heavy, and is much used in cabinetwork. It is also
used for dyeing a brilliant yellow. [Written also {jak}.]
